Macro partitioning
High intake of saturated fatty acids (SFA) from modern domesticated animal products and dairy increases LDL cholesterol and cardiovascular disease risk compared to ancestral diets rich in unsaturated fatty acids.
Prioritize unsaturated fatty acids (especially omega-3s) and fiber-rich foods over high-fat dairy and fatty cuts of domesticated meat. This shift aligns your diet with evolutionary norms and helps lower LDL cholesterol, reducing cardiovascular risk.
GoodSupportsHIGH confidence
A higher intake of high-fat dairy and meat products produces a divergent fatty acid profile that can increase the risk of cardiovascular and inflammatory disease... The effect of saturated fat on cardiovascular events is commonly attributed to LDL-C increases followed by accumulation in atherosclerotic plaque... Contemporary Americans have total cholesterol (TC) and LDL-C levels greatly exceeding those of HGs and other free-living primates
Why this rating
The paper cites multiple systematic reviews, RCTs, and cross-population observational data, though it acknowledges confounding variables in observational studies.

- Replacing saturated fatty acids with unsaturated fatty acids (specifically cis-PUFAs or cis-MUFAs) significantly decreases total cholesterol and LDL cholesterol levels.Strong
- High intake of saturated fatty acids from modern diets is linked to endotoxemia and inflammation, whereas unsaturated fatty acids do not produce this response.Good

- Resistance exercise training combined with sufficient dietary protein intake acts synergistically to maximize skeletal muscle hypertrophy, with protein intake saturating around 1.6 g/kg/day for general populations and potentially requiring 2.0-2.2 g/kg/day for resistance-trained individuals.Strong
- Trans fats should be completely eliminated from the diet, as they increase LDL cholesterol, decrease HDL cholesterol, and are directly associated with increased coronary risk.Strong
